Obstacles Overview

     Obstacles are objects that randomly appear in your base on a regular basis.  They are usually relatively cheap to remove, and can sometimes yield up to 6 gems each!  The cost of removal will depend on exactly which obstacle is being removed, this also affects the amount of time needed to remove the obstacle.  Here we will take a look at the various obstacles, their removal costs, and their uses.


Obstacle Types

There are 2 main types of obstacles:  Rocks and Plants.  The biggest difference between these is that once you remove a rock, it is gone forever, while plants will continue to return on a regular basis.  When you are first starting out in this game, this can seem frustrating because you don't have a lot of resources and these obstacles can pop up in the worst places; causing you to not be able to seal off an area of your village with walls or forcing you to place a building in a more vulnerable position.  But, as you progress through the game and you village grows in size and power, you will come to see these obstacles as a godsend, as they are one of the only sources of gems in the game apart from buying them outright, and as you grow the cost of removing them becomes a drop in the water compared to your stores of resources.  As a new player, you will notice that there are several obstacles surrounding the dilapidated clan castle on your village map.  You can focus on removing these first if they are in the way of your growing village, but keep in mind that once you restore the clan castle you will be able to move it anywhere you wish, so the obstacles really don't pose any problem for the clan castle.

There are also tombstones that appear after an attack at the spot your defenses killed a troop.  These can be tapped on for elixir or dark elixir depending on the type of tombstone (which depends on the type of troop that died there).  Make sure to clear these out after every attack, as potential attackers see un-removed tombstones as a sign of an abandoned base, which greatly increases the likelihood of them deciding to attack you.

Tombstones

Type	Size	Removal Time	Resource Received	Happens When
Tombstone	1x1	Instant	20 Elixir	Attacking/Defending Elixir Troop Killed
Dark Tombstone	1x1	Instant	1 Dark Elixir	Attacking/Defending Dark Elixir Troop Killed

There are also special objects that appear during special events and holidays.  Currently, these objects only appear for Halloween and Christmas, but in the future there will likely be others.  These holiday objects typically give you a great deal of resources compared to normal obstacles.  These objects can also vary from year to year, or may not even appear at all depending on what the developers decide to do on a given year. 

Special Obstacles

 

Type	Size	Removal Time	Removal Cost	Reward	Re-spawn Chance
X-mas Tree	2x2	30s	25,000 Gold	75,000 Gold	2%
X-mas Present	1x1	Instant	FREE	5,000 Elixir	N/A
Halloween Cauldron	2x2	30s	25,000 Elixir	75,000 Elixir	2%

This should give you enough information to pretty much be an expert on obstacles in Clash of Clans.  Good luck and clash on!!!
